Data inbound Escape special character incoming value can be a string or a one-dimensional array
Function Data_join (& $data)
{
if (GET_MAGIC_QUOTES_GPC () = = False)
{
if (Is_array ($data))
{
foreach ($data as $k = $v)
{
$data [$k] = addslashes ($v);
}
}
Else
{
$data = Addslashes ($data);
}
}
Return $data;
}

Data out-of-Library restore special characters incoming values can be strings or one/two-dimensional arrays
Function Data_revert (& $data)
{
if (Is_array ($data))
{
foreach ($data as $k 1 = $v 1)
{
if (Is_array ($v 1))
{
foreach ($v 1 as $k 2 = $v 2)
{
$data [$k 1][$k 2] = stripslashes ($v 2);
}
}
Else
{
$data [$k 1] = stripslashes ($v 1);
}
}
}
Else
{
$data = Stripslashes ($data);
}
Return $data;
}

Data display the Restore data format is primarily used for content output incoming values can be strings or one/two-dimensional arrays
You should data_revert () before executing this method, and the contents of the form need not be restored
Function Data_show (& $data)
{
if (Is_array ($data))
{
foreach ($data as $k 1 = $v 1)
{
if (Is_array ($v 1))
{
foreach ($v 1 as $k 2 = $v 2)
{
$data [$k 1][$k 2]=nl2br (Htmlspecialchars ($data [$k 1][$k 2]);
$data [$k 1][$k 2]=str_replace ("", "", $data [$k 1][$k 2]);
$data [$k 1][$k 2]=str_replace ("\ n", "
\ n ", $data [$k 1][$k 2]);
}
}
Else
{
$data [$k 1]=nl2br (Htmlspecialchars ($data [$k 1]);
$data [$k 1]=str_replace ("", "", $data [$k 1]);
$data [$k 1]=str_replace ("\ n", "
\ n ", $data [$k 1]);
}
}
}
Else
{

$data =str_replace ("", "", $data);
$data =str_replace ("\ n", "
